AppAdvice has teamed up with Tireless Weaver in order to offer you a chance to win one of five promo codes for WURM ($.99) for iPhone, iPod touch, and iPad.

WURM is one of those rare drawing apps that’s fun and accessible for those of us who aren’t artists while also being an inspiration to those who design by trade.

What makes WURM accessible is the fact that you can launch the app, have it randomly define every last setting, and then just let your fingers glide over the screen to create beautiful works of art. The app supports up to 10 fingers on the screen at once, so you can make your images as complex as you want. Once your work is complete, just double tap on the screen to bring the menu back up and send it off to your library to be used as a stunning wallpaper for your iDevice.

Tinker away!

If you are into tinkering, however, you’ll be happy to know that WURM is loaded with customization options. So many in fact that you may just spend hours tweaking settings to come up with the perfect image. The app allows you to choose from five different shapes and then manipulate their size, spin speed, opacity, mutation, density, and slant. You can also choose from and customize the different 10 color palettes. Shape and color configurations can be saved for later use as well.

To have a chance at winning one of two WURM promo codes, simply hit that blue tweet button near the bottom of this page or retweet this post from your favorite Twitter app before 11:59 PM PST tonight (November 30). We will then search the Twitterverse for all of the retweets and randomly choose our lucky winners. The winners will be notified via Twitter, so please be sure to follow us so we can send you your promo code via a direct message.

Non-Twitter users and those of you who want to increase your odds of winning can simply leave a relevant comment below before 11:59 PM PDT tonight to have a chance at winning one of the other three promo codes.

Feel free to participate in the giveaway via either or both methods. Only one entry per person per method is allowed, totaling up to two entries per person if using both.

Pretty picture.
